Fingerprint identification method, device, mobile terminal, and storage medium

Abstract

A fingerprint identification method, a device, a mobile terminal, and a storage medium, belong to the technical field of information processing technology. The method is applied to a terminal, response to detecting a touch operation on a specified application icon, obtaining fingerprint information corresponding to the touch operation; transmitting the fingerprint information to an application corresponding to the specified application icon; the application performing a safety authentication to the fingerprint information; and response to determining that the fingerprint information passes the safety authentication, the application entering an application display interface.

 transmitting the fingerprint information to the application; 
 in response to determining that the fingerprint information matches a pre-stored valid fingerprint information, determining, by the application, that the fingerprint information passes a safety authentication; 
 in response to determining that the fingerprint information does not match the pre-stored valid fingerprint information, determining, by the application, that the fingerprint information does not pass the safety authentication; 
 in response to determining that the fingerprint information passes the safety authentication, the application entering an application display interface; 
 in response to determining that the fingerprint information does not pass the safety authentication, calculating, by the application, the authentication failure times, the authentication failure times being the count of consecutive fingerprint authentication failures; 
 in response to determining that the authentication failure times reaches a preset count, blocking the specified application icon; 
 detecting a screen unlock operation when the terminal is locked and passing a screen unlock command to the application; and 
 in response to detecting the screen unlock command by the application, restoring displaying, by the application, the specified application icon. 
 
     
     
       2. The method according to  claim 1 , further comprising:
 after the application determines that the fingerprint information does not pass the safety authentication, the application shaking the specified application icon at a preset frequency, and displaying a fingerprint entry prompt message on the specified application icon, the fingerprint entry prompt message being configured to notify a user to re-enter the fingerprint information. 
 
     
     
       3. The method according to  claim 1 , wherein a fingerprint sensor is provided below a display screen of the terminal, and wherein obtaining fingerprint information corresponding to the touch operation comprises:
 launching the fingerprint sensor at the icon display area of the specified application icon; and 
 obtaining, by the fingerprint sensor, the fingerprint information corresponding to the touch operation. 
 
     
     
       4. The method according to  claim 1 , wherein in response to detecting a touch operation on a specified application icon, obtaining fingerprint information corresponding to the touch operation comprises:
 displaying a specified operation icon, the specified operation icon being configured to, upon being triggered, instruct the terminal to perform a specified operation, the specified operation icon corresponding to the specified operation, the specified operation being a function of an application corresponding to the specified application icon; 
 in response to detecting the touch operation on the specified operation icon, obtaining the fingerprint information corresponding to the touch operation. 
 
     
     
       5. The method according to  claim 4 , wherein displaying the specified operation icon comprises:
 displaying the specified operation icon in a desktop interface of the terminal; 
 or, displaying the specified operation icon in a notification bar of the terminal; 
 or, 
 displaying the specified operation icon in a navigation bar of the terminal. 
 
     
     
       6. The method according to  claim 1 , further comprising:
 when the terminal is in a state of screen on and locked, displaying the specified application icon in a user interface; 
 performing the step of responding to detecting the touch operation on the specified application icon, obtaining fingerprint information corresponding to the touch operation. 
 
     
     
       7. A mobile terminal, comprising a storage medium, a processor, and computer instructions stored in the storage medium and executable by the processor, wherein the processor is configured to perform:
 in response to detecting a touch operation on a specified application icon, obtaining fingerprint information corresponding to the touch operation, the touch operation being for decrypting an application corresponding to the specified application icon; 
 transmitting the fingerprint information to the application; 
 in response to determining that the fingerprint information matches a pre-stored valid fingerprint information, determining, by the application, that the fingerprint information passes a safety authentication; 
 in response to determining that the fingerprint information does not match the pre-stored valid fingerprint information, determining, by the application, that the fingerprint information does not pass the safety authentication; 
 in response to determining that the fingerprint information passes the safety authentication, the application entering an application display interface; 
 in response to determining that the fingerprint information does not pass the safety authentication, calculating, by the application, the authentication failure times, the authentication failure times being the count of consecutive fingerprint authentication failures; 
 in response to determining that the authentication failure times reaches a preset count, blocking the specified application icon; 
 detecting a screen unlock operation when the terminal is locked and passing a screen unlock command to the application; and 
 in response to detecting the screen unlock command by the application, restoring displaying, by the application, the specified application icon. 
 
     
     
       8. The mobile terminal of  claim 7 , wherein in terms of in response to detecting a touch operation on a specified application icon, obtaining fingerprint information corresponding to the touch operation, the processor is configured to perform:
 displaying a specified operation icon, the specified operation icon being configured to, upon being triggered, instruct the terminal to perform a specified operation, the specified operation icon corresponding to the specified operation, the specified operation being a function of an application corresponding to the specified application icon; 
 in response to detecting the touch operation on the specified operation icon, obtaining the fingerprint information corresponding to the touch operation.
